Jds file's Functions

• create

create("./", "test", { name: "Alex", age: 20 }, (err) => {
  if (err) {
    console.log(err);
  } else {
    console.log("Successfuly created the file");
  }
});

The first param take the path of the dir you want to create the file. And in your dir you will see a json file named as the second param. The second param takes the name on your file. And the third param takes the data of the file. Last param takes a callback.

And Give the dir as '../../' then as you want

And if the file exits. It will give an error like this.

[nodemon] restarting due to changes...
[nodemon] starting `node test.js`
There was an error, file may already exists!

• read

jds.read("./", "test", (err, data) => {
  if (err || !data) {
    console.log(err);
  } else {
    console.log(data);
  }
});

The first param takes dir as the create function and second param the file name that you want to read. And the third param takes a callback and it receive's two things, err and the data.

The output will be :

[nodemon] restarting due to changes...
[nodemon] starting `node test.js`
{"name":"Alex","age":20}

• update

jds.update("./", "test", { name: "Jon", age: 23 }, (err) => {
  if (err) {
    console.log(err);
  } else {
    console.log("Successfuly updated");
  }
});

It almost same as the create function. Just it updates the file. The output will be

[nodemon] starting `node test.js`
[nodemon] restarting due to changes...
Successfuly updated

• del

jds.del("./", "test", (err) => {
  if (err) {
    console.log(err);
  } else {
    console.log("Successfuly deleted");
  }
});

It almost same as the read function. But it deletes the file and in the callback it doesn't get the data. On output you will see:

[nodemon] restarting due to changes...
[nodemon] starting `node test.js`
Successfuly deleted

• makeArray

const numbers = makeArray(1, 2, 3, 4, 5, 6, 7, 8, 9, 10);

It will take the array values.

Hash file's funcations

• genHash

genHash("I like cake.");

The param takes the string that you want to hash. The output will be:

[nodemon] restarting due to changes...
[nodemon] starting `node test.js`

• compareHash

const hash = genHash("I like cake.");

console.log(compareHash("I like cake.", hash));

The first param takes the string and second param takes the hash string and it hashes the first param and match it with the second param and returns a boolean:

[nodemon] restarting due to changes...
[nodemon] starting `node test.js`
true

Have fun using the package.
